Sub-headline : The UK Labour Party’s ruling body has agreed to adopt in full an international definition of anti-Semitism, after months of rows.

‘It will incorporate all the 11 examples of anti-Semitism cited by the International Holocaust Remembrance Alliance into its code of conduct.

But Jewish groups have attacked an accompanying statement agreed by the NEC aimed at protecting free speech.

One warned it risked giving “racists a get-out-of-jail card”.

After a three hour meeting in London, Labour said its National Executive Committee had adopted all of the IHRA examples of anti-Semitism, including four it left out in July, alongside a statement ensuring “this will not in any way undermine freedom of expression on Israel or the rights of Palestinians”.

To riff on Shakespeare: ‘Cry havoc and let slip the dogs of Civil War’! Corbyn will either denounce this travesty, or he will betray the whole of his political career! The very pressing question of this moment!
